MoLA collected around 150 points using a TotalStation at this part f the bank in 1999. The coloured areas indicate the amount the bank has receded behind their points. The orange area, for example, has retreated by over 1 metre. The terrain model of the bank was created using a laser scanner and then removing the vegetation cover.
BGS is looking to include scan data from the island into their GeoVisionary system. This will integrate data collected from the Eyot with many different types of information, including geology, for the entire country.
